Welcome to DF
The PCM (Power Control Module). Ck your battery cables and you didn't State if the ck engine came on. Could be a flash or throttle body clean.

 

Negative on the check engine light.

Flash? Is this something that can be cleaned or is it a replacement item as well?

I assume the power control unit is a simple replacement? Any idea on cost of a PCM?

I'll clean the batt connections before I leave for my daily adventure. The dash lights never blinked off...

I'll get on cleaning the throttle body later today.

I am truly impressed with rapid response and in such a polite manner!!!

 

This is a very difficult problem to accurately asses a solution. See, inorder to fix things, the more information available the more accurate speculation is. A PCM is the Power Train Control Module... aka engine computer. Since you are obviously in tune with a computer I'll try my best to explain how the vehicle operates. As with any computer, operation is based on programming, inputs and outputs. When the vehicle is running properly, all inputs are in expected perameters, the programing or logic calculates this information to control the outputs, thus your car runs. If any one of these 3 basic sections has any defect or abnormal activity, proper operation is interupted. Say you unplug the printer... now it won't print. the input is the command from you to the computer then out to the printer. In this simplistic example the printer doesn't work because the output is unable to reach its destination. To repair this, hopefully you would check the obvious things like it being plugged in. In your vehicle this is something that would be checked by a quality technician... a visual inspection and grab and wiggle wires while it is running to see if the problem can be reproduced. Being your problem is intermittant, this greatly raises the complexity of the situation. So to pinpoint the possible causes, most technicians would utilize a quality tool called a scanner. This tool is able to see what the computer is doing and receiving. The more information that is available the obvious repairs will be easier to do. Basically you can throw parts at it or you can have it properly analyzed. and NO autozone and parts stores are not the way to go with this. A PCM will cost A LOT. I see lots of people posting on here prices in excess of $400 for one. And many find after that expense they still have the problem.

 

Thanks, I did not have time to check the Batt connection........

Will try that in a couple of hours.

I have access to a scanner ( a friend does a bit of car fix it work) so that is the next step.

 

Well I only had time to clean the batt connection, dumped in a container of water remover & injector cleaner. Drove the van as normal and only one time with in 3 miles did it have the micron stall.

I am going to have it scanned right after class today!

I'll post the results of the scan!

 

Not scanning for codes, you MUST scan the data stream. Look at the Misfire counts to see if it's one specific cylinder etc. Any quality scanner will do. When I diagnose this kind of problem, I drive the vehicle and when it acts up, I take a snapshot with my scanner. I get back to the shop, download into my PC and I can read all the data in graph form. Then I look for that anomolies causing it.

 

OH so now you want me to drive it around....... with it hooked up

Hmmmmmmm.

Anyhow here are the 2 codes for master tech using an ETHOS from Snap-On:
P0401 EGR system failure to affect F/A
P1281 Engine is cold to long

I can arrange to drive it around with the ETHOS but it has not had any issues since? Not like i'm gonna have my camera out ready at an instant to snap a photo when the typical micro stall lasts for less than 1 second other than the other night where it got real weird.

Thanks for your time Master Tech

 

EGR will give you a stalling problem. Replace the EGR and the t-stat too.

 

Thank you sir!

 

I'm going to tell you right now, you've pissed me off!! Your first statement is a snide remark. No crap you drive the car around with the scanner hooked up... that's called problem solving!!!. and real scanners have the capacity of taking a snap-shot and not with a fkn camera!!! I actually know exactly what the problem is with your van. I didn't want to GIVE you the answer, I wanted to see if you had enough whereabouts to figure it out with some guidance. Master Tech can provide the answer or Tizzy could cut and paste all the information related to you problem...since this is a very common and easy to fix.
